Nissan 240SX VIN prefixes, and when each one was used
The Nissan 240SX VINs on record carry 2 different prefixes. The main one is JN1 (Japan, 1989–1998), then JN3 (Japan, 1992–1994):

Where to find the VIN on a Nissan 240SX
A Nissan 240SX VIN normally opens with JN1; the full number sits in four places, and all four must match.
| Where | How to see it | Why it matters |
|---|---|---|
| Dashboard, driver side | Through the windshield, bottom corner | Easiest to check before you touch anything |
| Driver door jamb | Open the door, sticker on the pillar | Also lists tire pressures and build date |
| Under the hood | Firewall or strut tower plate | Survives a windshield replacement |
| Title and insurance | Paper documents | Must match the car — a mismatch means fraud or a swapped panel |

Frequently asked questions

Yes, with no account. Besides the year, plant and build characters it shows 2 recall campaigns and 133 owner complaints NHTSA holds on the Nissan 240SX.
Why does my 240SX VIN start differently from another 240SX?
Because the Nissan 240SX was built under several maker codes, by plant and period. Across the Nissan 240SX VINs on record we see 2 of them: JN1 (1989–1998), JN3 (1992–1994). Each is genuine for its years.
What year is my 240SX by its VIN?
Read position 10: a 2001 240SX carries 1, a 2000 240SX carries Y, a 1999 240SX carries X.
Where was my 240SX built?
Position 11 names the plant. Across 133 dated Nissan 240SX VINs it reads W 98%, C 2%.
What does position 4 mean on a Nissan 240SX VIN?
It is part of the maker's own build code, so read it against this model, not a generic chart. On 3 Nissan 240SX VINs here, H is the most common character in position 4, on 33% of them.
What if the VIN on the dashboard doesn't match the door jamb?
On a Nissan 240SX check the prefix first: most genuine ones open with JN1. A plate that starts with anything else, or disagrees with the other copies of the number, needs documents checked before any money changes hands.
